America’s most powerful supercomputer is a machine for scientific discovery. • The US Department of Energy’s Summit supercomputer enables scientists to simulate complex

physical systems and make predictions critical to advancing research and development.

• Summit’s “smart” architecture merges GPU acceleration and dense local memory to support expanding applications in data science and artificial intelligence.

BY THE NUMBERS

A 200-petaflop machine, Summit can perform 200 quadrillion (peta-) floating point operations per second (flops). If every person on Earth completed one calculation per second, it would take 305 days to do what Summit can do in 1 second.

For some AI applications, researchers can use less precise calculations than flops, potentially quadrupling Summit’s performance to exascale levels, or more than a billion billion calculations per second.

Summit’s file system can store 250 petabytes of data, or the equivalent of 74 years of high definition video.

Summit is connected by 185 miles of fiber optic cables—or the distance from Knoxville to Nashville, Tennessee.
